Probably closely related to P. capillatus. Race lucidus often considered a separate species, and maroccanus may also deserve consideration; however, while there is a superficial attraction in separating out these forms as species, given the distribution of white in the plumage and the subtler differences in green vs blue gloss and in size, these distinctions are unlikely to score sufficiently high under the system used herein, particularly as there is variation within taxa and a tendency towards intergradation at boundaries. Race novaehollandiae may be a separate species; alternatively, replaced by further races carboides (Australia) and steadi (New Zealand area). Race hanedae may be better considered synonymous with sinensis. Proposed race lugubris (E Africa) regarded as synonym of lucidus. Six subspecies normally recognized.
